A backflow preventer in your plumbing system, prevents water that flows through your pipes to flow back into the city water instead of going to the sewer system. The way this usually works is by creating an air gap, which works by eliminating a cross-connection or provides a barrier to backflow. One of the most basic mechanisms to prevent
backflow is a mechanical backflow preventer, which creates a physical barrier. The main types of mechanical backflow preventer are the reduced-pressure principle assembly, the pressure vacuum breaker assembly, and the double check valve assembly. A secondary type of mechanical backflow preventer is the residential dual check valve.
Whichever type of backflow preventer, we will replace existing mechanisms
that are outdated or broken.
A trained plumber can check your pipes and detect the following types of backflow:
- Gravity backflow
- Backpressure backflow
If your plumbing is old, make sure you have it checked for backflow and that deficient backflow preventers are replaced. Otherwise, you may be inadvertently drinking or otherwise using polluted water. Remember that showers, toilets, bidets, appliances, etc. all have a direct connection to the general water supply, that also flows out of the tap. Many people do not realize the importance of proper
backflow prevention, to prevent contaminants from water from entering the flow of drinking water.
